A wave-activated power generating apparatus in the form of a buoy includes a floatable main body provided with a vertically extending central pipe having its bottom open end opened into the water and its top open end located above the water surface when the main body floats in the water surface, an air turbine disposed at the top open end of the central pipe, a generator operatively coupled to the air turbine, and a plate-shaped guide plate fixedly attached to the main body as located opposite to and separated away from the bottom open end of the central pipe. The provision of the bottom guide plate allows to define a laterally opened circular opening between the guide plate and the bottom of the main body, through which the water moves into and out of the central pipe. This structure allows to use the present apparatus even in shallow waters.
